Sun Coast Cycle Sports carries used parts for the Kubota RTV-X1140, the updated generation of Kubota's convertible two-to-four passenger utility vehicle. In production from approximately 2014 to present, the RTV-X1140 runs the same Kubota D1105 three-cylinder diesel engine (24.8 hp, 1,123cc) as the earlier RTV1140 but with a significantly upgraded chassis featuring independent rear suspension. Parts from our donor fleet are inspected, individually cataloged, and ship from Florida.
RTV-X1140 platform and parts compatibility
The RTV-X1140 shares its D1105 diesel engine with the earlier RTV1100 and RTV1140/CPX models. Engine internals, filters, injectors, and glow plugs interchange across all 1100-class Kubota UTVs. The chassis is an evolution of the RTV1140 platform with the addition of independent rear suspension, revised body panels, and updated operator controls. The two-range (Low/High) VHT transmission replaces the earlier three-range system. Body panels, suspension components, and bed/seat conversion hardware are specific to the X1140 generation and do not fit the earlier RTV1140.
Common RTV-X1140 failure points and replacement parts
Convertible seat mechanism: The rear seat-to-bed conversion hardware sees regular wear. Latches and pivot points require periodic lubrication and inspection.
Front-mounted radiator maintenance: The X1140's front radiator is a major improvement over the earlier mid-mount design but still requires regular cleaning in dusty environments.
Independent rear suspension: The IRS system provides better ride quality but adds maintenance items including CV joints, axle boots, and bushings that wear with heavy use.
Diesel fuel system: Same fuel quality requirements as all Kubota diesel UTVs. Water separator draining and clean fuel are essential for injector longevity.

Frequently asked questions
Q: Will earlier RTV1140 parts fit an RTV-X1140
Engine components interchange since both use the D1105 diesel. Body panels, suspension, bed hardware, and convertible seat mechanisms are different between the RTV1140 and the RTV-X1140 due to the chassis redesign. Verify the specific model generation before assuming fitment.
Q: Does the RTV-X1140 have independent rear suspension
Yes. The RTV-X1140 upgraded to fully independent rear suspension, correcting one of the main complaints about the original RTV1140's solid rear axle. This change improved ride comfort but means rear suspension components are not compatible with the earlier model.
The RTV-X1140 improved on the original RTV1140 in several key areas. The most significant upgrade was the addition of fully independent rear suspension, which dramatically improved ride quality over rough terrain compared to the RTV1140's solid rear axle. The simplified two-range transmission (Low/High) replaced the seldom-used three-range system. Updated bodywork, improved operator ergonomics, and a revised ROPS cage rounded out the changes. The convertible two-to-four passenger capability carried over from the RTV1140, making the X1140 equally versatile for both work and passenger transport duties.
Q: What is the towing capacity of the RTV-X1140
The RTV-X1140 has a rated towing capacity of approximately 1,300 lbs and a cargo bed payload capacity of approximately 1,102 lbs. The hydraulic dump bed operates in cargo mode and can be actuated with a lever from the operator's seat.
Q: Does the RTV-X1140 have a cab option
Kubota offers both hard cab and soft cab options for the RTV-X1140 as accessories. The hard cab with heat and AC provides year-round comfort. Cab components are specific to the X1140 generation and do not fit the earlier RTV1140 or the RTV1100.
